Access your Google Calendar when offline

The new version of Calendar offline is only supported for Google Chrome. Download Chrome

Using Offline with Chrome 10+ Beta

Keep track of your time offline. With Offline Calendar for Chrome 10+ Beta, you can access your events through your browser without an Internet connection.

Thanks to Chrome's HTML5 and sync capabilities, you can now be offline and:

View calendars

RSVP to existing event invitations

So how does it work? Chrome simply stores your data on your profile while you're offline. Then, it syncs when you're back online. Currently, Google Calendar Offline is only able to sync two months of events.

To enable Offline Access:

Click the gear icon and choose Offline from the dropdown menu

You’ll be prompted to install the Google Calendar web application from the Chrome Web Store. Click Install from Web Store.

You’ll be taken to the Chrome web store page for the Google Calendar web application. Click the Install button.

The Google Calendar Web App download page opens in a separate window. If you accidentally closed it or it was prevented by a popup blocker you can try to open the download page again by clicking the Install from Web Store button in the popup again.

Once installation is complete, a new Chrome tab will open and the Google Calendar web app icon will appear. Click on the icon to be taken to Google Calendar.

Click the gear icon again. Next to Offline, you should see a green icon with a checkmark. This means your calendar is synchronized and ready to be used offline. If your calendar is still syncing, you’ll see a green spinning icon until it’s completed.

Your offline calendar will update every time you go online. Note: Offline will not work if you are using Chrome in an incognito window.

If you're having problems using Offline, check to see if you have your preferences set to clear cookies and other site data when you close your browser. You won't be able to use Offline if this preference is set. To change this setting:

Click the wrench icon

Select Preferences

Click the Under the Hood section

Click the Content Settings button

Uncheck Clear cookies and other site and plug-in data when I quit my browser

Keep in mind that you won't be able to use this feature if you're using another person's computer, and that person has already opted to use the feature. When this happens, you won't see the offline option in Chrome's drop down menu until the existing offline feature is disabled.

If you have multiple sign-in enabled, you can only use Calendar offline from one of your accounts. Before setting up this feature, make sure you're signed into the account you'd like to use offline. Also, make sure you're signed into the account you'd like to access offline before you disconnect -- once you're disconnected, you can't switch to another account.

To access your calendar when you’re not connected to the internet, you’ll first need to enable offline access using the steps above. If you have the feature enabled already, type www.google.com/calendar into your browser to access your offline calendar, or click the Google Calendar web application shortcut icon in a new Chrome tab.

If you lose connectivity while you're online, Google Calendar will automatically switch into Offline mode -- you don't have to do anything! When network problems are detected and connectivity is lost, you’ll see a message at the top of the calendar page letting you know you're offline, along with a link to try to reconnect.

Green icons indicate that you're online. The checkmark shows that your account is fully synchronized and it will stay green and spin while your events are synchronizing between your computer and Calendar servers.

Click the checkbox under Available Offline next to each calendar that you’d like to be able to view while offline.

If you see a calendar that is gray, that means it's hidden from your normal calendar view. If you’d like to make a calendar viewable, click the gear icon and choose Calendar settings. On the Calendar tab, click the checkbox to Show in list. You’ll then be able to add them to your calendars viewable offline.

To disable your offline access, click the gear icon and select Disable offline calendar from the drop-down menu. This will disable offline access and remove any data stored on your computer. It won't delete your events and other information from your calendar, though.
